Diamond M20 horizontal mill | The Hobby-Machinist

It is a Diamond M20 5x20 horizontal mill, and appears to be mostly unmodified and in very good condition for a 75 year old machine. I think it still has the original paint. It came out of a shop not far from the ocean, and there is almost no rust on it, so the prior owner must have given it a lot of attention.

Tool wear mechanisms in axial ultrasonic vibration assisted milling in ...

The in-situ TiB2 particle reinforced aluminum matrix composites are materials that are difficult to machine, owing to hard ceramic particles in the matrix. In the milling process, the polycrystalline diamond (PCD) tools are used for machining these materials instead of carbide cutting tools, which significantly increase the machining cost. In this study, ultrasonic vibration method was applied ...

Process for making diamond and cubic boron nitride compacts

Another possible variation is to effectively double the number of compacts made in a given sub-assembly by placing a refractory metal disc (e.g. zirconium) midway through the sub-assembly. For example, such a zirconium disc would appear in a sub-assembly in FIG. 1 as a horizontal element dividing a given sub-assembly into top and bottom halves.

The spindle power required for these machining operations is calculated in Eq. 8 for turning and in Eq. 9 for milling: (8) P Turn = T ω = 7.8 ( 400) 2 π 60 = 326 W, and (9) P mill = T ω = 4.55 ( 1500) 2 π 60 = 715 W. The power required for turning is continuous due to the nature of the process.

A V Carroll Horizontal Mill Rebuild - The Hobby-Machinist

I had a 1/2-10 acme nut from another project. The space under the milling table is 3/4" high and 1" wide. So I cut the nut down to a little under 3/4. I was a relief to be able to complete a simple task like this without a hacksaw or file. I hope those days are behind me. I touched up the cutter with a segmented diamond plate.

dimond tool co universal(?) milling machine. - Practical Machinist

The M-20 is a small size horizontal mill. It almost could be a benchtop machine, but it has a full cast floor base. It weighs maybe 800 lbs. On many of them, the horizontal overarm bar at the top has been fitted with a separate small vertical mill head. On one of mine, it's a Rotex head. Other guy's machines have other brand heads adapted to them.

Principles of Location in Jig & Fixture Design | Carr Lane

Whenever practical, position the locators so they contact the workpiece on a machined surface. The machined surface not only provides repeatability but usually offers a more-stable form of location. The workpiece itself determines the areas of the machined surface used for location. In some instances, the entire surface may be machined.

Serrations can cause component scratching in precision hard (no polishing pad) diamond polishing techniques. The serrations machined into the surface of a lap plate serve several purposes. The first is to limit the force of "surface tension". This force develops during lapping as the component contour begins to match the lap plate contour.
